Perhaps the most exciting Blu-ray release of the month is Paramount’s anniversary edition of Roman Polanski’s classic film noir homage Chinatown, which celebrates its 40th birthday this year (1972 was a helluva year for genre cinema). Polanski’s film — from a celebrated screenplay by Robert Towne — told the story of private investigator Jake Gittes (played to perfection by Jack Nicholson), and ended up revitalizing the private eye genre, which has continued to fascinate viewers to this very day. In our latest video essay, we’ve compiled over two dozen of our favorite movie detectives in tribute to one of our favorite movie genres. Check it out after the jump.
